To a/Z; whom, it may concern:

Be it known that I, WILLIAM FETZER, a citizen of the United States, residing at Middletown, inthe county of Butler and State l of Ohio, have invented certain new and usedesigned for the purpose of overcoming the Side draft, jarring, and excessivev neckweight incident to the heavy downward pulling of the ordinaryl disk-barrow tongue upon the neck of the Yhorses or other draft-animals and also to overcome thel dangers and possibilities of the outside horses (three or four being commonly used) getting their feet back into the disks, where they are liable to be seriously injured.

Novel characteristics of a convenient einbodinient of the invention include a twowheel tongue-truck on a disk liarrow; the fastening of the tongue proper at or below the stub-tongue on a disk liarrow; the fastening of the tongue of a disk liarrow between two truck-wheels; a jaw or hitch for fastening and securing the eveiicr-bar to the stub-tongue iii suoli a way as to prevent the evener-bar playing or turning beyond a certain degree, whereby to prevent the possibility of the horses getting back against the disks, as above suggested; a tongue-truck for disk hariows having a universal-joint fastening between the truck and the harrow; a disk harrow with a truck suitable for Jfastening the tongue below the eveneiis;`a disk harrow with tongue-truck and an adjustable vhitch for hitching high or low according to a large or small size team; pull-hounds extending from the center of the disk-sections up to the hitch and immediately under the stubtongue, whereby to provide a very direct hitch, and the wheels of the truck having the surface thereof ridged in the center and narrowed to both edges, whereby dirt and mud will not stick thereto, and the saine will, in effect, be self-cleaning.

All the foregoing features of my present invention, as also the details of construction and arrangement of the several paits of the machine constituting the before-mentioned convenient embodiment of the invention, will be apparent from the detailed description hereinafter contained, when read in connection with the accompanying drawnigs,

forming part hereof, and wherein such machine is illustrated.

In the drawings, Figure 1 is a sectional view; I*`ig. 2, a top plan View, and Fig. 3 a side elevation.

Referring more specifically to the drawings, wherein like referencecharacters refer to corresponding parts in the several views, A represents the frame of a disk harrow, which may be of any ordinary or preferred construction; B, the harrow-disks, and C a stub-tongue projecting forwardly from said frame and disks.

D are pull-hounds, one at each side of the stub-tongue and secured to the forward end portion of said stub-tongue through the medium of a coupling E, bolted to the under surface thereof by a bolt c, said coupling havtion of and within which the ends of the pullbars are secured, pins e being provided therefor.

The rearmost extension cl of the pull hounds or bars are straight, as at d, so as to enter between a pair of the disks of each harrow-section, approximately at the center thereof, and be secured to the uprights or brackets a of the fi'aine A, the manner of fastening -the parts together being clearly shown at d. Of course the main portion'of each of the pull-hounds is offset with respect to the extension d and inclined forwardly and inwardly therefrom to the strbtongue C, to which latterit is secured, as hereinbefore stated.

F represents the tongue-truck, the saine comprising a pair of wheels G, the engaging ridged and narrowed or beveled toward the edges of the wheels,wliereby theywill be selfcleaning, it being practically impossible for dirt and mud toaccumulate-to any substantial extent on'such peripheries.

I is the axle of the truck, which passes through and is clamped within a two-part casting, which -will now be defined. K is the bottoni half of this casting, which has a groove lseniicircular in cross-section in its r pper surface adapted to receive the axle I and a for-l ward extension i, flanged at its edges, as at i', forming a seat withinwhich the tongue proper, K', fits, and is bolted, as at i .ing separated ears e at its ends for the recepsurfaces or periplieries of which are centrally IOC J is the upper member or part of the casting i io ing devices,

rigidly carried by and preferably formedintegrally with a combined supporting-arm and brace-M', the lower end of which is approximately vertically disposed and flanged, asat m, for a purpose as will presently appear, while the "upper end of which .is bent rearwardly slightly andl offset at its upper ex tremity to immediately underlie the stubtongue C and overlie the coupling E, whereby the securing means for 'said cou ling also serves as a securing means for sai offset extremity, as will be apparent from an inspec tion of Fig. 3. This combined supportingarmand brace M cooperates with a strap of metal N to constitute a support-for an adjustable clevis or hitch O, the relation of the member M and strap N being such that they mutually serve to strengthen each other.

As will be appreciated from the drawings, the strap N overlies and is secured tothe upper surface of the stub-tongue through the medium of a horizontal portiori'ard also depends and is rigidlysecured to the member M through the medium of a vertical portion, the 'uncture between the horizontal and ver: tical portions being carried forward beyond the front end of the stub-tongue, whereby to afford a space P, within which the clevis O may be slipped up and down to accommodate a large or small size team. The clevis is provided with clamping means o and a pivot-pin o, on which the `evener-bar is mounted to swing to a limited extent only, the rear sides, of the clevis preventing said evener-bar playing or turning beyond a certain degree, thus preventing the ossibility of the horses getting back against t e disks B.

By locating the tongue K below the eveners any interference on the part of the latter to the operation of the device is obviated.

The universal connection for the tonguetruck, while permitting the same to conform to irregularities of ground-surface, serves the additional and valuable function of relieving the bearing of the extreme pressure and strain incident to the leverage inherent in an association of parts in a rigid structure-as,

for instance, where a single truck-wheel is l carried by a swivel-postY It is also to be noted that the two-wheeltruck idea is believed to he fumlainental in this art, and the advantages thereof, though perhaps apparent, may he stated to be the making practical of a single-wheel device,

which latter when alone relied on is disposed to sink down into soft or muddy ground and also to creel, especially after the bearings have become loosened up a little, and which encies has nobearings'adequate to hold it.

l The special arrangement of the parts of the combined disk harrow and tongue-truck herein described or as specified in the claims, with the tongue proper secured 'tothe truck at a pointbelow the plane of the axis of the disks or at a point located within the planes of the axis of the disks and the lower edges thereof or at a point to exert a downward pressure on the truck and stub- 'tongue when the tongue proper is subjected to backward .pullH or at a oint adjacent the plane of the axis of the dis rs possesses a highly-desirable characteristic in that practically all tendency of the stub-tongue and truck to rock upon the disks and be forced upwardly and rearwardly incident to the backward pull on the tongue, as would be the case where the tongue proper is secured to the truck at a point substantially above the plane of the axis of the disks, is effectually overcome and the 'function of effecting a downward pressure'on the forward end ofthe stub-tongue and 'truck during suc'h backward pullof the tongue proper secured.

I claimj 1. The combination with a support, vof harrow-disks thereon, a stub-tongue projecting forwardly from a point ,above the disks, a truck comprising a pair of wheels universally connected to the forward end of said stubtongue, and a tongueproper secured to said truck at a point below the plane of the' axis of the disks and projecting forwardly from the truck, in combination with a hitch arranged above the truck. n

2. The combination with a support, of harrow-disks thereon, a stub-tongue projecting disks, a truck connected to the forward end of said stub-tongue, and a tongue proper secured to said truck at a point located wlthin lower edges thereof and projecting forwardly arranged above the truck,
